NAITO Yume Nikki

Meta Knight played a ROM hack of Yume Nikki where all the characters were replaced by SARP characters.
But instead of jumping off a roof, he jumped out of Doug Funnie's ass.
Yeah, this was a weird plot.

After Party Poopers, plotholes literally started springing up all over the place. Kefka managed to escape from the Godlike Safety Capsule in this manner, and Meta Knight was sucked into another. This was originally a joke, as the only seeming way to get out of an "inescapable" place would be to screw the rules well, actually, yes. To screw the rules.

When Meta Knight stopped being warped, he found himself in a room similar to Madotsuki's. So Meta Knight went on an adventure exploring his own fucked up dreams.

Meta Knight first found Tabuu in the Numbers world rubbing a pole. He was then offwaved.

Meta Knight then found himself on a spaceship where Claus Masada pinched him and woke him up.

Meta Knight, along with the ROLEPLAY CHARACTER and Skeeter, were then farted out of Doug Funnie's ass. ROLEPLAY CHARACTER and Skeeter farted off to gather Chaos power with Mickey Mouse.
Meta Knight, freed from his dreams, went back to the demolished remains of the League HQ, kicking off the Liquid Lindsey plot.
